SPECIFICATION. forming part of Letters Patent No. 636,408, dated November '7, 1899. Application iiled May 8,1899. Serial No. 715,906. (No model.)

To a/ZZ wiz/0m, t may concern.-

Beit known that I, MAX HURVITZ, a citizen of Russia, and a resident of New York city, county and State of New York, have invented new and useful Improvements in Brushes, of which the following is a specification.

This invention relates to a brush which is more particularly adapted for cleaning cylindrical bodies, such as bicycle-tires, tubes, and similar articles.

The body of the brush is ofa curved form,

Aso that it fits the article to be cleaned, and its back is made of a bendable material which permits its adjustment to articles of dilferent diameters. j

In the accompanying drawings, Figure 1 is an end View of my improved brush; Fig. 2, a section online 2 2, Fig. l; and Fig. 3,l an end View of the brush, showing it bent to a dierent diameter.

The tufts a project radially inward from a back or lower plate b, made of leather or other flexible material, which is curved into an approximately semicylindrical form. The back is at its edges embraced by the anged ends c of a correspondingly-curved top plate c, to the outer side of which the handle d is attached. The top plate is composed of soft or bendable sheet metal, the curvature of which may be readily changed by an inward or out-v ward pressure against its ends and which when once bent willretain its shape until a new contour is imparted to it. In this way the brush may be set to snugly it tubular objects of different diameters, Fig. 1 showing the brush in a distended form and Fig. 3 in a more contracted form, but of course an indefinite npmber of interm'ediateor more extreme forms are obtainable.

Theend tufts a should be somewhat longer than the others, and the front and reartufts a2 should project at an obtuse angle outward beyond the edges of the back, as shown.

My improved brush is`well adapted for cleaning cylindrical objects, and owing to its bendablecharacter the same brush may be used with full effect upon objects of dierent diameters. l

What I claim is-f A brush composed of an outer curved softmetal plate, a handle secured thereto, and a flexible platesecured to the inner side of the metal one, combined with the tufts @,the outer rows of tufts d', which are longer than the ones a., and the ones a2 which are inclined outwardly, substantially as described.
